The mitotic spindle is built from
A.microtubules
B.actin filaments
C.DNA strands
D.lipid bilayers
Explanation
Core Concept
The mitotic spindle is made primarily of microtubules that interact with chromosomes through kinetochores and with other cellular structures to organize chromosome movement. In animal cells, centrosomes are major microtubule-organizing centers, but many plant cells organize a spindle without centrosomes. The universal feature is the microtubule spindle, not centrosome nucleation in every eukaryote.
Correct Answer
Amicrotubules
